Detailed description of the invention
Below with reference to accompanying drawings the embodiment of the intelligent automatic heat radiation electric control box of the present invention is described in detail.
Street lamp, shows the light fixture that road provides illumination functions, refers to the light fixture in the illumination zone of road surface in traffic lighting.
The formal mankind attempt carrying out artificial lighting on avenue and start from the beginning of the 15th century.1417, in order to allow London winter black night become clear evening, Mayor of London's Henry bar paused and issues order, it is desirable in outdoor suspended lamp illumination.Later, his proposal had been got back French support.When 16 beginning of the century, outside Paris residential building window at the front, lighting must be installed.During Louis 14, the street in Paris occurs in that many street lamps.1667, city illumination decree was also formally promulgated in the Louis 14 being referred to as " sun king ".Exactly because the promulgation of this decree, the governance of Louis 14 is just referred to as France's historical " bright epoch ".
The road that street lamp is night brings light, and for night, the walking of pedestrian provides the good visual field, also gives people's security simultaneously, and especially at each traffic intersection place in city, the quantity of street lamp is maximum.Although the power consumption of single street lamp is not high, but the feature short owing to having spacing distance in the distribution of street lamp, the overall energy consumption of the street lamp in each city is very high, if ensureing that Urban Residential Trip is convenient while, effectively reduce the street lamp power consumption in city, be one of the municipal administration department in each city problem of wishing to solve.
Owing to the street lamp in each city is large number of, whole power consumption is huge, especially maximum at the street lamp distributed quantity at each traffic intersection place.Lacking the technical scheme that neighbouring street lamp carries out open and close control based on real-time pedestrian's quantity in prior art, open and close control model used is excessively fixing, and intelligent level is not high.When being so easily caused without pedestrian, too much LED street lamp still by fixed model illumination, causes the waste of city LED street lamp resource.
In order to the switch of the LED street lamp at traffic intersection place is controlled, need to introduce and control hardware accordingly, such hardware device is it is generally desirable to be arranged on scene, to ensure real-time and the accuracy of data, but for each traffic intersection, common equipment is inherently many, and except pedestrian, vehicle pass-through space, remaining space is very limited, increases a set of data acquisition and data communications equipment newly at each traffic intersection place, unrealistic.
In order to overcome above-mentioned deficiency, the present invention has built a kind of intelligent automatic heat radiation electric control box, utilize the control chamber of existing traffic intersection, while increasing automatic heat radiation equipment, transform to increase on-site data gathering equipment and field data communication equipment to it, instant switch service is provided in time, it is to avoid occur that the situation of the city LED street lamp wasting of resources occurs for each LED street lamp neighbouring.
